The utility model provides a pair of concrete patching machine dust device, enclose into the enclosure space through installing the suction hood on the patching machine with the equipment organism, the dust that prevents equipment production flies upward everywhere, the dust fall processing is conveniently concentrated to the while, form suction to the dust hood through the air exhauster, and it connects into the large granule to be the dust through subsequent atomizing, and through filter screen multi-stage filtration, discharge clean air after advancing the dust bag at last, this device can collect respectively the dust fall processing of carrying out to the material dust that shakes of feed inlet and the rotatory dust that produces in the organism, can play very good dust fall effect, be fit for using widely in the mine capital construction field.
Drawings
The invention will be further explained with reference to the following figures and examples:
fig. 1 is a schematic structural diagram of the present invention.
In the figure: the dust removal device comprises a pulp shooting machine 1, a dust hood 2, a feed inlet dust hood 21, a machine body dust hood 22, a horn cover opening 23, a dust suction opening 3, a feed dust suction opening 31, a machine body dust suction opening 32, an exhaust fan 4, a dust fall pipeline 5, an atomizing nozzle 6, a dust removal bag 7, a primary filter screen 8, a secondary filter screen 9, a dust fall cavity 10 and a pressure release valve 11.
Detailed Description
As shown in fig. 1, a concrete patching machine dust device, include the suction hood 2 of being connected with 1 base of patching machine, be equipped with dust absorption mouth 3 on the suction hood 2, dust absorption mouth 3 is connected with air exhauster 4, air exhauster 4 exit end is connected with dust fall pipeline 5, dust fall pipeline 5 upper end is equipped with atomizer 6, dust fall pipeline 5 exit end is connected with dust bag 7, seal around patching machine 1 equipment through suction hood 2, the dust that equipment produced flies upward everywhere, produce the dust absorption air current through air exhauster 4, then carry out the dust fall through 6 spun water smoke of atomizer and handle, collect the processing through dust bag 7 to the dust that does not atomize at last.
As shown in fig. 1, the dust hood 2 is divided into a feed inlet dust hood 21 and a machine body dust hood 22, the feed inlet dust hood 21 is located above the feed inlet, the feed inlet dust hood 21 is provided with a bell mouth 23 facing above the feed inlet, the machine body dust hood 22 is located between the base and the feed inlet, the feed inlet dust hood 21 and the machine body dust hood 22 are respectively provided with a feed dust suction port 31 and a machine body dust suction port 32, the feed dust suction port 31 and the machine body dust suction port 32 are converged at the inlet of the exhaust fan 4, dust generated at the feed inlet is different from dust generated at the machine body of the shotcrete machine 1, the feed inlet generates flying ash during adding raw materials, vibrating material dust generated at the lower end of the feed inlet is inhibited by the bell mouth 23, the vibrating material dust is discharged through the feed inlet, the vibrating material dust and the flying ash are absorbed through the feed dust suction port 31, and concrete slurry is formed by the machine body of the internal rotation of the equipment and the friction mechanism of the materials, dust seeps through the body rotation slit during rubbing and is thus collected by the body dust hood 22.
